Y sIrHoN BOTTLE Y l Application led November 1, 1928. y Serial No. 316,581.

This'invention relates to Siphon-bottles or jars particularly ofthetype described in my copending application for Siphon bottle, Serial' No. 240,062, iiled December 14, 1927 :g5 The object of the invention. is tosimplify i i 2.1.5 ploy a discharge spout as the manipulator forcontrolling byits position all the valve action, and as'an additional feature, the sej curing of the spout when in non-discharging position so. as to yfunction as a serviceable t @carrying handle. A further object of my invention isvto reduce the cost of construction and amountof material required in the embodiment of parts capable of carrying out the function of a self-charging and dischargyThe above and vfurther objects of my invention will be pointed out more particularly f in the following claims'which'are directed to an illustrative embodimentof my invention 30 described in the following specification in connection with the accompanying kdrawings solelyfor purposesof illustration and not limitation. Y l

`In Vthe drawings, Fig. 1 is a plan view of i .35 my improved cap structure. Fig. 2is a section through line II-II of Fig. 1. Y Fig. 3

is a vertical section taken through line III-III of Fig. 1, parts being shown in elevation and parts being broken away. Fig.

o 4 is a fractional view similar to Fig. 3 showing the discharge positionforthe discharge spout, andFig. 5 is a top yview of the siphon tube with its mounting nipple. v f' n My cap structure A comprises a threaded t0 Iiange 1 to Vengage about a complementary l form of neck of a suitable Siphon bottle such as that shown in my copending application Videntified above and is closed across the top E: by alledge 2 upstanding from which is ay ."10 cartridge housing 3 provided with a threaded end'4 to mountthe usualcartridge voperator and which is capable when` open of tending to force compressed gas, such as carbon l dioxide gas, through the portj.r`

Adj acent, the end ofthe cartridge housing 3 isl formed' a; valve housing '6 perforated from top to bottom and having an interior wall 7 lwhich is cylindrical in they generic sense,'kbut which preferablyisvthat type of cylinder known as a conical surface Withthe this valve housing is ahy-pass 8 leading upwardly froml the spacel at the bottom of the valve housing. The cap structure 'in the bottomof the valve housinghas a cylindrical enlargementv i9V preferably threaded to take the mounting nipple r10 towhich is securedin anyj'suitable manner as soldering and c from which depends the usualsiphontube '60, taper extending. upwardly. In the wall of or stem 11k. `rThis threaded nipple 10 is pro? Y vided with a Adiscontinuous seating .ledge j12,

thel opening 13 `iny which forms apport between the interior 14 of stem 11 yand the by-pass 8.,V

/ VAdapted/to work within the valve housing 6 is a complementary conical valve 2O mount,V 5 Y fing atits top adischarge spout .21 ywhich Yserves as an operator to swivel the valve20; f Y'llhe valve 20`is provided witha duct 22'leadingv from they lateral port* 23'and is also provided vwith. a duct 24 leading from the port 25. `Along the top of the cartridgehousing 3 is preferably providedy Van upstanding 'holding y.

lip formation 3() adapted to'cooperate with Van outstanding flange or 4beading 31 :formed about' the discharge end of the spout 21 and servingto reinforcev thespout 21 whenv it functions v,as a carrying handle.

.In the position of the apparatus yshown Fig. 3, thexport vis in communication with the passage 14Vthrough-the siphonstemll if: sothat gas under pressure from the car` tridge `mounted in *the cartridge housing Y S may have entrance into the liquid contained in thesiphon bottle r'and by flowing therein f under pressure `effects the charging'thereof.

2O vin the valvehousing is effective in resist-i n'this position the discharge spout 21 is disi dispensedk v ....MMJr

Ving the internal pressure of the charged liquid.'

In Fig. 4, the construction is shown in discharge position in which the'spout 2l has been turned 180 from its Vposition in Fig. 3 to close the charging port 5 and open the discharge connections for the spout 2l. For example', by-pass 8 is now in communication with ports 23 and 22 to eect an opening between the interior 14 of the siphon stem and vthe discharge spout.

It is preferred that the valve housing, cartridge housing and cap structure be fabricated as a single die casting of suitably strong metal such as a zinc or aluminum alloy.

The valve 6 may be a di-e casting, as likel wise the nipple l0.Y The siphon tube l1 may beI metal or glass if desired, in whichcase Va `jsuitable packing washer between itdand the nipple lmay'be desired. Y

They spout 21 mayy conveniently be `formed of a bed piece of metal tubing presse-d or soldered into the valve 6. f

What I claim and desire to secure by VUnited States Letters Patent is:

1. In a cap structure for siphon bottles.V

- valvehousing above and communicating with said v(')peningg means providing a cartridge mounting being provided with acharging port leading into said valve housing ;a single swiveling valve member rotatably mounted in said valve housing and carrying a. discharge spout Aand being provided with valve ducts a-ndvalve ports capable in one position of opening communication between' said charg-. ing port and said `siphon'stem and closing communication between said siphon stem and said discharge spout and in another position Vclosing `communication to said charging4 port and opening communication between saidl siphon stem and said discharge spout.

.2. In combined charging and discharging apparatus osphon bottles, a cap structure providing a cartridge housingrand a cylindrical valve seat providing a through opening' from the outside to the inside of said capi structureY and having ports in its walls; a discharge spout having a rotating valve at its bottom and swiveled in said' valve seat to cooperate withsaid ports. saidvalve having Vports and passages alternately to establish communication between said charging housing and the liquid chamber and between said Vdischarge spout and th-e liquid chamber.

3. A cap for siphon bottles having a cartridge housing and a valve housing; a siphon tub'ependent from said cap andy communicating with the interior of said valve housing; a single rotary valve member, a discharge spout mounted' as an extension of said valve y member-'and constituting an operator therefor; said valve member and said valve housing being provided with cooperative ports whereby a manipulation of said spout between discharge position and charging position serves as the sole means for controlling the entrance and exit from said siphon bottle of the liquid Vto be dispensed and the opening of communication between the liquid to be charged and a charging cartridge.

y 4.' In a'siphon bottle7 an upwardly or out- `wardly tapered conical valve member having control ports and passages; a combined discharge spoutand handle fixed and carried by said conical valve; a valve housing providing aconical. seat for saidvalve 'and having two sets of ports cooperating with'said valve, the one functioning for the entrance of charging charge of liquid. f Y

.5. In asiphon bottle, means for charging liquid with a gasunder pressure and for disgas and the other' functioning for the .dis-- charging the charge d liquid comp-rising means,

dfor mounting a cooperating cartridge of compressed gas; and a single valve member'for controlling all fluid entrance and eXit from said siphon bottle.

In witness whereof, I have signed my name to this specilication7 this 31st day of October,
